STEP 2: INSTALLATION PROCEDURE:
PLEASE READ THIS MANUAL BEFORE
ATTEMPTING TO INSTALL, OPERATE OR MAINTAIN THIS EQUIPMENT. HAZARDOUS VOLTAGES ARE PRESENT INSIDE
TRANSFER SWITCH and LOAD CENTER ENCLOSURE THAT CAN CAUSE DEATH OR SEVERE PERSONAL INJURY. FOLLOW PROPER INSTALLATION, OPERATION AND
MAINTENANCE PROCEDURES TO AVOID HAZARDOUS VOLTAGES. TURN OFF THE MAIN CIRCUIT BREAKER IN THE LOAD CENTER BEFORE STARTING INSTALLATION.
A. Install contactor (Item A) into manual transfer switch:
1. Referring to Figure 1, determine the appropriate location to install the contactor inside the manual
transfer switch enclosure, based upon the manual transfer switch model determined in STEP 1.
Clean the location from all dirt and grease. Remove the double-stick tape backing on the contactor
and press the contactor tight to the enclosure. Make sure that the wires attached to the contactor
are accessible for routing and termination.
B. Terminate NC1 and NC2 in load center (electrical panel):
2. Locate the 67” gray wires marked NC1 and NC2 connected to the contactor. For PRE-WIRED and
VINTAGE manual transfer switch models, route, insert and feed both wires into and through the conduit located at the bottom of the
transfer switch. For POWERSTAY models, after the wire harness conduit has been attached to the transfers switch, insert and feed both
wires along with the wire harness into and through the conduit located at the bottom of the transfer switch. For all models, terminate wires
NC1 and NC2 to the load center neutral bus bar. See Figure 2 Wiring Diagrams for all wire routing and connections.
